3x-5y=22: y=-5x+32 solve for y

Answer:

39.

Step-by-step explanation:

78% of 50 is 39. To calculate x% of a number y, we use the following rule: x% of y = (x / 100) × y.

Answer:

138.5°

Step-by-step explanation:

A peach pie is in the form of a circle. The sum of angles in a pie is equal to 360°.

Since there are 13 peaches evenly distributed, therefore each peach occupies 360/13 degrees.

Joe ate one slice of pie that contained exactly 5 peaches, hence:

Angle measure of slice = (number of peaches in the slice / total number of peaches) * 360°

Angle measure of slice = (5 / 13) * 360°

Angle measure of slice = 138.5°

Step-by-step explanation:

Answer:

Length of the fence required = 135 m

Step-by-step explanation:

Total length of the fence required to cover the vacant lot = Perimeter of the isosceles trapezoid

Perimeter of ABCD = AB + BC + CD + AD

Since, AB = BC = EF = ED = 25 m

From the given right triangle BEC,

m∠EBC = m∠ECB = 45°

ΔBEC will be an isosceles triangle.

So, BE = EC

By Pythagoras theorem,

BC² = BE² + EC²

25² = 2(EC)²

EC = [tex]\frac{25}{\sqrt{2}} =17.7[/tex] m

And DC = (DF + EF + EC)

             = EC + EF + EC [Since, DF = EC]

             = 2EC + EF

             = 35.4 + 25

             = 60.4 m                            

Hence. perimeter of ABCD = 25 + 25 + 60.4 + 25

                                              = 135.4 m

                                              ≈ 135 m

Therefore, length of the fence required = 132 m

==========================================

Explanation:

The same tickmarks on each side of the triangle tells us that all three sides are the same length. This triangle is equilateral.

All equilateral triangles have each of their three angles at 60 degrees (they are considered equiangular). This is because 60+60+60 = 180.

Set 2x+32 equal to 60 and solve for x

2x+32 = 60

2x = 60-32

2x = 28

x = 28/2

x = 14

As a check,

2x+32 = 2*14+32 = 28+32 = 60

which helps confirm the answer.

Answer:

i believe it is 17.

Step-by-step explanation:

if c is 8 am, then 7 am must have been at 10. so add up all the numbers from then and further back, and you get 17. (it could also be 7 so don't count on it)

Answer:

4x and (1-y)

Step-by-step explanation:

4x(1-y)

this is my answer

The factors of the expression are 18x and 4-y

Given the expression 72x - 18xy

Find the factor of each term:

72x = 18 * 4 * x

18xy = 18 * x * y

Since 18x is common to both terms, hence the factored form is expressed as:

72x - 18xy = 18x (4 - y)

The factors of the expression are 18x and 4-y

Answer

the answer would be

D(5,-2).

Answer:

D(-6, 1)

Step-by-step explanation:

To determine the solution we can start by calculating the slope of AB;

A(-1, 4), B(2, -5)

m = -5 - 4 / 2 - (-1) = -9 / 3  = -3

Then CD, if to be perpendicular, should have the 'negative reciprocal' of the slope of AB. In other words it should have a slope of 1/3. We are given point C as (3, 4) so let's take each of the given options for point D, and find the slope using the two points. If the slope is 1/3rd then that  is the correct option.

Now I already know the answer, so instead of going through all the options I will just check the slope with the correct answer choice. You will find the slope to be 1/3rd;

C(3, 4), D(-6, 1)

m = 1 - 4/- 6 - 3  = -3/-9 = 1/3rd

Correct, as you can see

So your solution is option c
